Be it known that L Dnxnzn.. Lowxm, :i citizen of the United States. residing in the citjv and coixnty of San Francisco and Stateof Clifornia, have invented neu' and useful impl-(nements 'in Dump-Bodies -f`or '\'ehiof which the following is n specification. This invention relates to nqrlumplmtly for rucks, and piirticnlarly.pertains to n mech-` :mism forl operating saine,

,It iS the object of this linvention tn Per vide va mechanism fonnpernting a roclnthle dump-body inwhich thev use of upwardly' i :sive height is obviated, but which. however', is :adapted to elevate the free end of the dumphndy ,to a snflicientl distance to insure the discharge of the loud. v

A further nhject is to 'provide n mechanism of the above' character which is simple in construction -and efficient and reliable in operation. and which' is s0` constructed :ind arranged as to -reqitire no shortening of the dump-body to provide space for its, gippliriv. tion.l

Another ohjec't'nf this invention-is tn pr 1- vide Ineansfor elei'nting the free end nfgi pivoted dnmp-bfidy",in which the. lifting forcelvvil'l he e'xertedin the forni of n pull substantially ina direction along the line of the are of travel ofthe {minf nfnpplicnf tion of the )wer to the dump-hody.

The inventionV further cnnsih'ts of zxrts and the rnntructinu und eumhimitinn iled and claimed. having reference to the :ii-companying drawings. in'\\jhicl..-

Figure 1 is a partial side elevation of a truck. shaking the invention as' applied. Fig. :2 is a. 'transverse section und elevntinn on the line rtv-a of Fig. L Fig. 3 'i5 detail the mechanism for rinsing and lowering the' and Side elevation of the operating gears.

In the drawings repreents n truck-- frame or chassis, and B represents n dumphody pix'otally mounted at '2 thereon. The dump-bdya is here shown as the. enddumptype, Whiehis designed to be elevated at iisY forward end torischargei its contents from its rear'end.

IThe essence of this invention resides in forward end of the dump-bodyS which mechanism consists of a pair of standards 3 mounted on the truck-frame A on each the rearward nf the. Standards 53.
